I've pushed in a large number of 2.6 patches for the Au1x. The Db1500 is
now very usable and almost completely up to date, including pci, pcmcia,
usb host, audio (oss), and mtd. The rest of the Db1x boards will follow.
There are a few patches in my directory that are needed, until Ralf
approves them and applies them. The directory is
ftp.linux-mips.org:/pub/linux/mips/people/ppopov/2.6. The 36 bit patch
is mandatory; the ide patch is nice but not mandatory; the zImage is
also optional; the pcmcia patch is mandatory if you're going to use pcmcia.

I'll apply the pcmcia patch after some additional testing and then get
rid of the patch. The driver now does not require the 64bit pcmcia patch
that was hard to get accepted in the community tree. The patch uses the
current fixup_bigphys_addr() mechanism, which was already in place
anyway. Thanks to Matt Porter for the simple but brilliant suggestion :)
